Bolts are widely used in daily life, but their application is not very clear. Let us introduce bolt manufacturers in detail:

1。 The key of headless bolt is non-metallic material and riveting.

2。 The key point of semi tubular bolt is riveting with small load.

3。 Core bolt is a kind of bolt used for single and double side riveting, semi hollow stainless steel rivet, but this kind of bolt must be used together with some special tools. This kind of bolt is very suitable for the place where the general bolt is not convenient to use.

4。 Tubular bolts are used for riveting non-metallic materials.

5。 Signboard riveting key for riveting equipment, machinery and equipment and other factory nameplates.

6。 The key bolt is another kind of bolt with single and double riveting. When riveting, the bolt head must be knocked with a hammer. When the core is exposed, the top is flush and riveting is carried out. This kind of bolt should not be used. General bolt or core bolt.

7。 The key of small flat head friendship head bolt is non-metallic material, such as metal sheet, white canvas and wood. Large flat head bolt is used for riveting non-metallic materials.

Although one of the small bolts is not worth mentioning, the semi hollow copper rivet plays a very important role. According to the simple detailed introduction above, I believe that the bolt has a simple grasp.

It is very easy to have problems in the whole process of riveting. Some of these problems can be prevented. I will analyze the situation with you.

In the whole process of application, sometimes there will be a transmission condition. The reasons for this kind of situation are that the core tensile strength is too large, the screw diameter is slightly small, the bolt material is soft, and the surface layer of the bolt body is excessively moistened; after the bolt is riveted, the burr of the smashed core of the steel nail crosses the hole of the riveting body; or the good protruding of the bolt hole produces the burr of the scraping hand. The key reason for the burr of the semi hollow countersunk head rivet is that the diameter of the journal cover is slightly smaller, the raw material of the bolt is too soft, the diameter of the product workpiece is slightly larger, the specifications and models of the nozzle of the rivet gun are inconsistent, and the key bone fracture and the spacing between the nail cores are very large, which is beyond the specific riveting thickness.
